Bottle Top Dispenser for Your Lab

Practical Tips for Choosing the Bottle-top Dispenser for Your Lab

Bottle-top dispensers are commonly used in various laboratories to measure liquid (typically between 1 and 60 ml) from a reagent bottle. Because they are used in so many different lab settings, there can be many factors to consider when choosing the right bottle-top dispenser for a particular set of needs.  

A few questions to consider when shopping for the right bottle-top dispenser:  

  • Which chemicals will this bottle-top dispenser be used for – and will it be durable enough to tolerate them?  
  • Is this bottle-top dispenser easy to clean and calibrate?  
  • What is the nominal volume for this unit?  
  • Does this bottle-top dispenser have ergonomic controls to allow for ease of use? 

A bottle-top dispenser is a long-term investment, so it is a good idea to consider all factors when choosing the unit to best suit your laboratory needs.
